System, method, apparatus, control method thereof and computer program for wireless communications

A wireless communications method for forming a wireless network group per user in which a plurality of terminals capable of wireless communications exist, each of said terminals is capable of a receiving user's memory device detachably inserted therein, said method comprising the steps of:

• authenticating, whereby each of said plurality of terminals reads respective ID information held on the respective certain user's detachable memory;
• and
• constructing a network whereby each of said terminals forms a wireless network group with a communication destination having ID information equal to that read from the memory device,
• wherein each of said terminals, in said step of authentication, writes its own operating information thereof in said memory device when receiving said memory device, and/or, reads operating information of another terminal written by said another terminal, and shares said operating information of each of said terminals, and
• wherein said operating information is at least one of a data format, a media attribute, a transmission rate, a demodulation method and a frequency band that can be used by the terminal.

A wireless communications apparatus forming a wireless network group per user and carrying out wireless communications under an environment in which a plurality of terminals capable of wireless communications exist, said apparatus comprising:

• a wireless communications unit transmitting and receiving wireless data;
• a memory device interface capable of receiving user's memory devices detachably inserted therein, wherein:
• each of the plurality of terminals constituting the wireless communications network includes the detachable memory interface and authentication is performed by reading respective ID information from respective certain user's memory devices received in said memory device interface, and
• a wireless network group is formed with a communication destination in accordance with said ID information;
• and
• a memory region to save operating information thereof and/or operating information of the communication destination, wherein:
• after writing said operating information of a terminal thereof in said memory device received in said memory device interface and/or reading said operating information written by other wireless communications terminals,
• wireless communications are carried out according to said operating information, and
• wherein said operating information is at least one of a data format, a media attribute, a transmission rate, a demodulation method and a frequency band that can be used by the terminal.

A control method of a wireless communications apparatus having a memory device interface capable of receiving user's memory devices detachably inserted therein, forming a wireless network group per user, and carrying out wireless communications under an environment in which a plurality of terminals capable of wireless communications exist, each of said terminals is capable of receiving the user's detachable memory devices, said method comprising the steps of:

• authenticating, whereby each terminal receives said user's detachable memory and reads respective ID information held therein;
• and
• constructing a network for forming said wireless network group with a communication destination in accordance with said ID information,
• wherein in said step of authentication, operating information of a terminal is written in said memory device is written, said operating information written by another terminal is read to carry out wireless communications according to said operating information after said wireless network group is formed by said step of network construction, and
• wherein said operating information is at least one of a data format, a media attribute, a transmission rate, a demodulation method and a frequency band that can be used by the terminal.

A computer-readable medium encoded with a computer program which is written to execute on a computer system processing to form a wireless network group per user by a wireless communications apparatus equipped with a memory device interface capable of receiving user's detachable memory detachably inserted therein under an environment in which a plurality of terminals capable of wireless communications exist, each of said terminals is capable of receiving the user's memory device, said program comprising the steps of:

• authenticating, whereby each terminal receives said user's memory devices and reads respective ID information therein;
• and
• constructing a network for forming a wireless network group with a communication destination in accordance with said ID information,
• wherein each of said terminals, in said step of authentication, writes its own operating information thereof in said memory device when receiving said memory device, and/or, reads said operating information of a terminal written by said another terminal, and shares said operating information of each of said terminals, and
• wherein said operating information is at least one of a data format, a media attribute, a transmission rate, a demodulation method and a frequency band that can be used by the terminal.
